Overview
AAR PRECISION SYSTEMS is an operational stormwater outfall in Huntsville, Alabama, serving the aerospace manufacturing sector under US EPA NPDES MS4 regulations.
AAR PRECISION SYSTEMS operates a stormwater outfall located at 140 Sparkman Drive in Huntsville, Madison County, Alabama. This facility manages stormwater runoff from an industrial site classified under NAICS codes 336413 and 336419, which cover aerospace-related manufacturing. As a stormwater outfall, it discharges collected runoff into local waterways, subject to federal and state regulatory oversight. The facility operates under the US EPA National Pollutant Discharge Elimination System (NPDES) Municipal Separate Storm Sewer System (MS4) framework, which governs stormwater discharges from industrial and municipal sources. In Alabama, the Alabama Department of Environmental Management (ADEM) administers the NPDES program, requiring permits that specify monitoring and pollution prevention measures. The site's industrial catchment likely involves runoff from manufacturing processes, parking areas, and impervious surfaces. Stormwater management at this facility is critical for protecting water quality in the Tennessee River watershed, which receives runoff from Huntsville's industrial and urban areas. Proper treatment and control of stormwater help reduce pollutant loads such as sediments, heavy metals, and hydrocarbons that can impact aquatic ecosystems and downstream water uses. The facility's compliance with permit conditions supports local environmental goals and community water resources.
Environmental context
The outfall discharges into the Tennessee River basin, a region with diverse aquatic habitats and downstream water supply uses. Huntsville's industrial sector, including aerospace manufacturing, contributes potential pollutants like metals and petroleum hydrocarbons to stormwater runoff. Regulatory oversight under the Clean Water Act and Alabama's NPDES program aims to minimize these impacts through best management practices and monitoring.
